Jim, I think that Alan K2WS has plotted the drift of his SDR-1000 and found that the biggest effect was when TRANSMITTING. The PA and enclosure seemed to heat up quite a bit. The fan then cooled it down and the master oscillator swung up/down in freq with the temp. If I remember correctly, the Tx and Rx temps were quite different. He used an OCXO to stabilize both to within a very small margin (tenths of a Hz?). de ken n9vv
